    This Dairy-Free & Keto Key Lime Pie with a simple spiced crust is a summertime dessert favorite! It's extra creamy and perfectly sweetened with the right amount of tart.

    If you love citrus desserts like these Keto Lemon Bars and Glazed Lemon Poppyseed Bundt Cake, you will LOVE this Dairy-Free & Keto Key Lime Pie!

    It's easy to make, extra creamy, and has a graham cracker style crust with the perfect sweet/tart ratio!

    Key limes are a bit smaller and pack more of a punch than regular limes and are the star ingredient. However, key limes can be harder to find so this recipe will work with any limes you can find!

    The keto sweetener

    For the crust, I use an erythritol-based keto powdered sweetener. I use an erythritol-based sweetener because otherwise, the crust will turn out too soft.

    For the filling, any keto powdered sweetener should work. I always use Powdered Monk Fruit Erythritol Blend since that's what I use for the crust.

    If using a non-erythritol sweetener, you may need to cover the crust with a crust protector because the pie will take a bit longer to cook.

    For Paleo, you can powder some coconut palm sugar. Just make sure the blender is completely dry! It will slightly affect the color and give it a slight caramel taste but will work.

    How to make dairy-free key lime pie

    To make a dairy-free key lime pie, simply sub the condensed milk with coconut cream!

    For the coconut cream, place a can of full-fat canned coconut milk in the fridge for 24 hours then scoop out the coagulated cream.

    I only recommend Thai Kitchen, Sprouts, and Native Forest brands because other brands may not separate well or have a funny aftertaste.

    The crust

    Preheat oven to 350 degrees.

    Then, whisk together some almond flour, cinnamon, powdered sweetener, and salt in a large bowl and some melted butter (can use non-dairy or ghee).

    Stir the melted butter and an egg into the dry ingredients and press into a lightly greased pie pan.

    The mixture will be crumbly, however, if it's too crumbly to stick together, add more butter as needed.

    Bake around 8 -10 minutes, or just until starting to brown.

    The filling

    Add freshly squeezed lime juice, lime zest, powdered sweetener, and coconut cream to a blender or food processor - starting with the lowest amount of lime juice and sweetener.

    Blend and taste. Limes can vary a lot, so taste the filling and add more lime juice and sweetener as needed.

    Once you have the tartness and sweetener how you like, add the coconut flour, eggs, and egg yolk then mix well.

    As soon as the crust comes out of the oven, pour in the filling. By adding the filling to the hot crust, it keeps the filling from seeping into it.

    Bake at 350 degrees for 20 to 25 minutes, or until the center is set.

    Allow to cool to room temperature, then place in the refrigerator to finish setting up. This will take approximately an hour.

    Serve with Dairy-Free Coconut Whipped Cream and Enjoy!!

    💭 Top tips

    • Start with the lower amounts of sweetener and lime juice then taste the pie and add more as needed. Lime juice can vary a lot in taste, so tasting and adding more as you go will ensure the perfect sweet/tart ratio every time.
    • While not required, I highly recommend blending in a food processor or blender. This will ensure a creamy pie that cooks evenly.
    • To keep the filling from seeping into the crust: 1) Don’t poke holes in the crust when pre-baking and 2) Pour the filling into the crust and bake as soon as the crust comes out of the oven. If the crust puffs up while pre-baking, gently press it down before pouring in the filling.
    • Please, please USE FRESH LIMES and not the reconstituted stuff, it's just not the same!
    • For the sweetener, I use an erythritol-based keto powdered sweetener in the crust. I use an erythritol-based sweetener because otherwise, the crust will turn out too soft. For the filling, any keto powdered sweetener should work. I always use Powdered Monk Fruit Erythritol Blend since that's what I use for the crust. If using a non-erythritol sweetener, you may need to cover the crust with a crust protector because the pie will take a bit longer to cook. For Paleo, you can powder some coconut palm sugar.

    Instructions

    Key Lime Pie Filling:

    • In the jar of a blender or food processor, combine the lime zest, coconut cream, and the lower amounts of fresh lime juice and powdered sweetener. Briefly blend. Then, taste and add more lime juice and sweetener as needed. Remember, the taste will slightly mellow after baking.

    The Crust:

    • Preheat oven to 350 degrees.
    • Whisk together the almond flour, cinnamon, sea salt, and powdered sweetener in mixing bowl. Add the melted butter and egg. Mix until combined.
    • Press the crust into a lightly greased 9-inch pie pan, going about 1 ½ inches up the sides. Bake around 8 -10 minutes, or until the crust is just starting to brown. If crust starts to puff up, gently press it down before pouring in the filling.
    • Add filling to the crust as soon as it comes out of the oven. Bake for 20 to 25 minutes or until the center is set, but still soft.
    • Cool for around 30 minutes, then transfer to the refrigerator to finish setting up. This takes approximately 1 hour.
    • Serve with coconut whipped cream.
    • Store covered in the fridge for 3 to 5 days.

      I love this recipe! I honestly had "diet food" expectations, but when I took the first bite, it was instantly one of my favorite desserts. My husband also loves it, which is saying a LOT because he normally doesn't like anything citrus based!

      Hey Cassidy, it’s been a while sense I used this recipe. I thought it used agave for the sweetener instead of a powder. Did you change that’s? If so can you remind me of how much agave I would use?

        Sadly, when I posted my Keto Key Lime Pie version I accidentally deleted the original version. Luckily, I had shared a few of my original recipes on Tasty Kitchen! Here is the link to my original recipe that uses honey or agave: https://tastykitchen.com/recipes/special-dietary-needs/dairy-free/dairy-free-key-lime-pie/

      Hi I just pulled this out of the oven at 25 minutes and it’s a soupy mess I did not set up at all is it going to somewhat set up after I chill it? Or should it have already done something by now

        I had the same problem! Ive made several key lime pies in the past but with evaporated milk, non coconut creme. I wonder if that is why its not setting up? Too much oil?

          Amy & Erica,

          I'm SO very sorry this recipe didn't work for you!!!

          I've made this recipe many times and it's always turned out, but after your reviews I decided to test the recipe again. I tested it several times and it seems that not every time, but occassionally, it doesn't quite set up. And I definitley don't want a recipe that only has a 80% success rate - it needs to be 100!!!

          To ensure that it NEVER happens I slightly adjusted the recipe. Again, I'm SO VERY sorry this didn't work for you. However, I hope you will try it again! Thank you very much for your feedback.

          -Cassidy

      Thanks for the awesome recipe ! Just made it, and the only think I changed was I added a little more sugar, because the filling was a little too tart, but that's just a matter of preference. Also was wondering if you used lime zest from the key limes. or did you use zest from regular limes ? I've never used key limes before, and was thinking that maybe their zest is more potent than regular limes are. I'll try cutting back on the lime zest next time. We're so excited to have this recipe, and it will be used often !

        YAY Debbie, I'm so happy liked it!!! Yes, I did use regular limes so if you used key limes that's probably why yours was so tart - sorry bout that! I'll make a note in the recipe saying I used regular limes 🙂

      I made this for my family for Easter and it was fabulous! No one else there other than myself has problems with wheat and dairy, but everyone loved it. Well, they would have preferred a normal crust, but they all could not believe that the pie was dairy and sugar free. YUM! Highly recommended!

      withoutadornment- You can definitely taste the lime but I didn't think it was too strong or overwhelming. If you prefer just a hint of lime you can always reduce the lime juice by 1 or 2 tablespoons. Hope you like it 🙂
